Documentation

Cookies should be configured securely using the http-only and secure settings.

Session cookies are frequently the target of Cross-Site Scripting (XSS) attacks. By setting the setUseHttpOnlyCookie() flag to true (which is also the default setting), the cookie cannot be accessed by client-side scripts.

Before
cookie.setUseHttpOnlyCookie(false);
After
cookie.setUseHttpOnlyCookie(true);
